ROOF GLAZING STRUCTURE Hans Briggen,

Vienna, Austria Application November 8, 1935, Serial No. 48,914 In Austria November 16, 1934 13 Claims.

This invention relates to a roof glazing or skylight structure in which the use of putty or any cement is dispensed with. One object of this invention is to provide a roof glazing or skylight structure in which the overlapping edges of adjacent glass plates have sufficient freed-om of relative movement for enabling them to automatically adjust themselves in accordance with any variations of strains and dilatations and contractions to which these plates may be subjected, the roof glazing structure or skylight structure being nevertheless maintained perfectly water tight. Another object of the invention is to provide a roof glazing or skylight structure in which there are no connecting elements, such as screws, rivets, wedges or the like on the outer side of said structure.

With these objects in View according to this invention the overlapping edges of the glass plates are supported on curved and preferably elastic surfaces of superimposed supporting elements, the relative position of the glass plates and said supporting elements being maintained by springs engaging each other and one of said supporting elements, one of said springs being secured to said supporting element.

The invention is also applicable when a second glazing is arranged inside an outer glazing, the two glazings having in common the supporting elements.

The invention is illustrated in the accompanying sheet of drawing in which Fig. 1 is. a vertical section of a preferred form of a single glazing according to the present invention, while Fig. 2 is a similar View of a preferred form of a double glazing according to the present invention.

The overlapping glass plates I3, I 4 are preferably provided at their edges with flanges i5 perpendicular to the body of said plates and serving for leading off rain water or condensed water to the eaves drops. The lower glass plate I 3 rests on the supporting surface 3 mounted on a supporting element l which may consist of a glazing rod, the parts being so shaped that the glass plate may rock on the supporting surface without interfering with its intimate contact with said supporting surface 3. A bar shaped cushion I6 is interposed between the edges of the glass plates I3, I4 overlapping each other, this cushion bar being located as nearly as possible vertically to the supporting element I. The plane bottom side of the cushion I6 rests on the lower glass plate I3, while the top side of the cushion I6 serves as a bearing for the upper glass plate I4 and is suitably curved for enabling the glass plate M to adjust itself relatively to the glass plate I3 by rocking on the top side of the cushion I3 or by sliding over the same.

- The cushion I6 and the supporting surface 3 are preferably made of an elastic material for instance of a hemp core with a lead covering as usual in the art or of a material not hitherto used for the purpose, consisting of some fibrous material such as hemp impregnated with a bituminous emulsion throughout or on its surface only. This latter material is superficially adhesive, so that the glass plates adhere thereto thereby improving the operation of the structure.

The cushion I6 and the supporting surface 3 and the glass plates I3, M are held in their proper relative position by springs I 2 and I I of which the spring I2 is held in position on the body of the supporting element or glazing rod I by screws, wedges or the like. The spring I2 passes round the flange I5 of the lower glass plate I3 and its upper end enters between the glass plate I3 and the cushion I6. The end of the spring I2 bearing on the top side of the glass plate I3 is provided with an upwardly directed rib engaging into a corresponding groove in the bottom side of the cushion I6 for holding said cushion'in position above the supporting element I. The other spring I! engages also below the cushion I6 and is also provided with an upwardly projecting rib engaging into the same groove of the bottom side of the cushion as the similar rib of the spring I2 as above explained. The spring I'I passes round the free edge of the upper glass plate l4 and holds this plate I4 against the cushion I6.

Instead of providing the springs I2 and I! as just described, the glass plates can be directly connected to the supporting elements by ce-' inenting.

In the construction shown in Fig. 2 the head of the supporting element I is provided with a groove 2 receiving the supporting surface 3. Thereby the supporting surface 3 is more reliably locked against lateral shifting relatively to the supporting element without, however, interfering with the free adjustability of the glass plates relatively to the supporting element I.

The bottom flange 4 of the glazing'rod serving as the supporting element I is provided with turned up edges supporting soft cushion strips 5, 6 on which rest the glass-plates I, 8 located on opposite sides of the supporting element I the edges of which cannot overlap each other, but are in the same level. For preventing accidental movements of the glass plates 'I','8 they are held against the cushioning strips 5, 6 by springs 9, l0 secured to the supporting element I by the screw II which serves for securing the spring [2 which holds the lower glass plate l3 of the outer glazing layer against the supporting surface 3. The glass plates 1, 8 constitute the inner glazing layer.

The cushioning strips 5, 6 consist preferably of the same elastic material as the cushion bar and the supporting surfaces on which rest the glass plates constituting the outer glazing layer.
